100 Endgames You Must Know by Jesús de la Villa

There are, contrary to what most amateurs believe, relatively few chess endgames one must know. Jesus de la Villa, an international grandmaster and former champion of Spain, presents the endgames that show up most frequently in practice, are easy to learn and contain ideas and concepts that are useful in more difficult positions. He brings you simple rules, guiding ideas at the beginning of each chapter, detailed and lively explanations, many diagrams, clear summaries of the most important themes, recommended exercises that will help you understand the material, and tests, divided in two parts: basic and final. The main thing De la Villa asks of you is to always understand WHY you play a move.
